Slant six 1920 stall

Latest update,
I finally got a chance to get back on the Dart this week.
A couple of weeks ago I installed an electric choke so that part is taken care of now.
I tried to check fuel pressure with my pressure/vacuum gauge. Tee'd into the fuel line with the tee supplied with my gauge but it is a like 1/8" tee and my line is bigger. Tried to clamp it shut be it leaked and the plastic tee broke.
I also tried to get the idle down to 600-700 but it still will run ok there then drops dead. It seems to want to idle 1-1.2k rpm and seems to be ok but going lower results it it dying.
I drove it around yesterday and when running does fine but coming to a stop it still wants to die. I did notice something funny to me, if I hit the brakes hard when coming to a stop the engine seems to want to die also. I know a vacuum booster leak would likely cause this but the car is all manual so it seems weird to me.
It is idling roughly also, tried adjusting idle control to no avail.
I also sprayed some starter fluid at the throttle bushing area and it would speed up leading me to believe the holley is worn.
I am so tired of fighting this because it hurts my body too much, Im ready to push it into the lake, anyone have a 2 barrel carb in the pacific northwest they would like to rent so I can check this out or would be willing to lend a hand?
